Geochemical effect of Asmari Oil Reservoirs on Masjed-e-Solaiman Karstic Water Resources


Department of Geology, Faculty of Earth Sciences, Shahid Chamran University of Ahvaz, Iran


Adjacent of water resources of karstic formation with oil felids can contaminate this resources. Due to important of water resources in hard formation, investigation of these effects is very important. In this way, study of geochemical effect of oil reservoir on water resource carried out using geochemical and hydrogeochmical studies in the Masjed- e- Solaiman area. Result show that chloride -sodic and sulfate- sodic are types of waters and they are insufficient for drinking water. Analysis of normal alkanes and sediments show that the concentration of heavy metals are Ni>Zn>Cr>V>Cu>Pb>As>Co and the source of oil materials are asmari reservoir of MIS oil field which is decomposed, intensively, Result indicates that water resources in Asmari formation are result of mixing of soluble water of Gachsaran formation and brine water of hydrocarbons. Investigation of this mixing can be useful for decreasing of contaminations and increasing of quality of Garo spring and Tembi River.
